The bq20857 is a custom device; therefore, we cannot provide unseal keys.

Hi. I'm writing from Poland. I have dell battery with bq20857 controller. I have software for bq20857 and I have unlocked successfully it. I have read it, dynamic data, and dataflash, but battery is broken. Battery shine all 5 leds constantly, when I push test button flash 1,3,5 led. I think that something wrong, in some fields are only 0. I post screens of sbs section, and data flash section. Please look at this and guide me how to repair this battery. Please help. Sorry for my english.

Hi, In order to make it work you have to Clear Permanent Failure because you have SOV bit set in Permanent Failure Status Register and then reset the gauge.

Good Luck.
